YEJ系列矩形膜盒壓力表簡 介
YEJ-101型矩形膜盒壓力表適用于鍋爐通風設備對銅合金不起腐蝕作用的和中性、無爆炸危險的氣體的微壓和負壓進行測量。
YEJ-121型矩形接點膜盒壓力表是適用于鍋爐通風設備對銅合金不起腐蝕作用的和中性、無爆炸危險的氣體的微壓和負壓進行測量并具有雙二位調節（雙線發訊）的作用，以實現位式調節或超限作用。
Brief Introduction:
YEJ-101 model rectangular membrane case pressure meter is applicable to measure micro-pressure and negative pressure of neutral gases without danger of explosion, which cause no erosive attack on copper alloy.
It is also applicable to measure micro-pressure and negative pressure of neutral gases without danger of explosion in boiler draft equipments, which cause no erosive attack on copper alloy. In addition, it has a function of dual two-position adjustment （message sent by dual line）, so as to realize position
